Dogs can tell the difference between happy and angry human faces, according to a new study in the Cell Press journal Current Biology on February 12. The discovery represents the first solid evidence that an animal other than humans can discriminate between emotional expressions in another species, the researchers say.

"We think the dogs in our study could have solved the task only by applying their knowledge of emotional expressions in humans to the unfamiliar pictures we presented to them," says Corsin Müller of the University of Veterinary Medicine Vienna.
